With the rapid development of technology, children's concentration has gradually declined. Visual Land was developed to use children’s free time at home to improve their ability to focus, overcoming the shortcomings of current treatment methods. It incorporates eye scanning technology with games to train children while keeping them engaged. The training content of the games are divided into three categories: graphic identification, numerical calculation, and language learning. The training data is also provided to parents to help them understand the progress of their child. In addition, via cloud transmission, the therapist can review the current training achievements and adjust the training scheme accordingly.
